1. Push the      Turbine/Motor Selector Switch, and the green lamp will light up and the air 

turbine will be selected.

2. • When the auto cruise mechanism is OFF :

Depress the      Knee Controller or the      Pedal, and the turbine will rotate.

• When the auto cruise mechanism is ON:

Push the      Auto Cruise Switch and depress the      Knee Controller or the      Pedal, and 
after a lapse of two seconds, the turbine will continue rotating even if the      Knee 
Controller or the      Pedal is released.

3. To cancel the auto cruise mechanism, depress the      Knee Controller or the      Pedal again 

or push the      Auto Cruise Switch.

Even if      Forward/Reverse Selector Switch is pushed while using the air turbine, it will be 
neglected only with the beeps of electronic sounds.

4. Push the      Turbine/Motor Select Switch again, and the lamp will go out and the motor will 

be available.

For the use of a small-diameter round bur or 
fisher bur at 40,000min

-1

(rpm) or more, pressing 

the Speed Limit Release Button, which is 
equipped with the      Speed Control Knob, and 
turning the speed control knob allows a setting 
of up to 50,000min

-1

(rpm). (Fig.7)

5. Operation Procedure of Air Turbine 

(Option)

When the motor is operated with a load exceeding the limit or the handpiece is in an 
unrotatable condition, the circuit to protect the motor and unit operates to stop the power 
supply to the motor, whereby an error code appears on the      Indicator.

How to reset the protective circuit

It can be reset by depressing the      Knee Controller or      Pedal again after eliminating the 
cause of the error.

6. Protective Circuit

When the      Power Switch is turned on, the rotation direction made when the switch was last 
turned off are restored. Special attention should be given to the rotation direction.

7. Memory Function

When the motor is stopped due to some trouble such as a failure, overload, wire breakage or 
misuse, Speed Display displays the error code for checking the status of the unit and 
understanding the cause of the trouble easily.

8. Error Code

Fig. 7

CAUTION

Use of 40,000min

-1

(rpm) or more is allowable only when the bur manufacturer or dealer 

specifies that the bur's acceptable rotation speed is 40,000min

-1

 (rpm) or more. If the 

use of more than the acceptable rotation speed is made, the bur may be broken.

Cause

• Abnormal internal memory
• Broken internal memory
• Long-time use at a high load (overcorrect)
• Shorted cord (power line)
• Shorted motor winding
• Failure of a turbine adapter
• Shorted cord (power line), damaged circuit
• Broken internal circuit
• Failure of a turbine adapter
• Faulty sensor (Hall IC) in the motor
• Disconnected motor cord
• Severed cord (signal line)
• Open chuck
• Faulty handpiece
• If the cord of the turbine adapter is loosed.
• Temperature rise in the unit due to longtime 

use at a high load

• Unit placed under high temperature
• Abnormal voltage generated in start / stop 

circuit

• Faulty start / stop circuit from PAM (L Slide)
• Open chuck
• Faulty handpiece
• Motor Faulty
• Faulty sensor (Hall IC) in the motor
• Severed cord (signal, power line)
• Long-time use at a high load (overcorrect)
• Shorted cord (power line)
• Shortstop of the motor winding
• Failure of a turbine adapter
Faulty motor and circuit
• Faulty Foot Pedal or Shorted Foot Pedal cord 
• Broken internal circuit
